DSG3000 Programming Guide

To Output RF signal

Requirement

Use the SCPI commands to realize the following functions:

Output a RF signal with 1 GHz frequency and -40 dBm amplitude from the [RF OUTPUT 50Ω] connector.

Method

1.

*IDN?

/*Query the ID string of the RF signal generator to check whether

the remote communication is normal*/

2.

:SYST:PRES:TYPE FAC

/*Set the preset type to "Factory"*/

3.

:SYST:PRES

/*Restore the instrument to the factory setting*/

4.

:FREQ 1GHz

/*Set the RF signal frequency to 1 GHz*/

5.

:LEV -40

/* Set the RF signal amplitude to -40 dBm*/

6.

:OUTP ON

/*Enable the RF output*/

To Output RF Sweep Signal

Requirement

Use the SCPI commands to realize the following functions:

Output a RF sweep signal from the [RF OUTPUT 50Ω] connector by configuring continuous linear step

sweep. Set the frequency range to 1 GHz to 2 GHz, the amplitude range to -20 dBm to 0 dBm, the number

of sweep points to 10 and the dwell time to 500 ms.

Method

1.

*IDN?

/*Query the ID string of the RF signal generator to check whether

the remote communication is normal*/

2.

:SYST:PRES:TYPE FAC

/*Set the preset type to "Factory"*/

3.

:SYST:PRES

/*Restore the instrument to the factory setting (by default, the

sweep mode is continuous, the sweep type is step and the

sweep spacing is linear)*/

4.

:SWE:STEP:STAR:FREQ 1GHz

/*Set the start frequency of step sweep to 1 GHz*/

5.

:SWE:STEP:STOP:FREQ 2GHz

/*Set the stop frequency of step sweep to 2 GHz*/

6.

:SWE:STEP:STAR:LEV -20

/*Set the start level of step sweep to 20 dBm*/

7.

:SWE:STEP:STOP:LEV 0

/*Set the stop level of step sweep to 0 dBm*/

8.

:SWE:STEP:POIN 10

/*Set the number of step sweep points to 10*/

9.

:SWE:STEP:DWEL 500ms

/*Set the dwell time of step sweep to 500ms*/

10. :SWE:STAT LEV,FREQ

/*Enable the frequency and amplitude sweep functions at the

same*/

11. :OUTP ON

/*Enable the RF output*/
